If the quality of the twist stick is not good, you can try to contact the merchant for return or complaint.

You can also consider repairing or processing it yourself, such as gluing the cracked parts together, or using sandpaper to polish the surface.

In addition, you can also try DIY to make your own twist stick, choose high-quality materials, and make it according to the correct method to ensure quality and safety. Most importantly, do not continue to use the twist stick of poor quality to avoid accidental injuries.
